Are you too passionate to be a good boss?

Passion is near the top of most lists of must-have leadership traits, but you can have too much of a good thing, writes Mike Myatt. Passion can lead to emotional overinvestment, distorting judgment with disastrous consequences. "Just as there exists a very fine line between brilliance and insanity, there also exists a fine line between passion and many negative traits such as narrow-mindedness, narcissism, fanaticism, delusion, and even paranoia," Myatt writes.
